Suggested January 2024 How To Hack The Alarm System Of A Smart Car?

Apart from insane drivers and unforeseen road problems, owners of these smart cars will also have to consider the possibility that someone is attempting to take control of their vehicle remotely. That isn’t just a speculative possibility.

Smart Cars are convenient, but are they safe?

Smart antitheft systems, in principle, are more than just alarms. Even if the vehicle has already been taken, they can help. They can track it, turn off the engine, and lock the doors before the cops arrive, for example. And it’s all done with the help of a smartphone app.

Convenient? Yes, absolutely! Safe? As the manufacturers claim, such technologies were created to increase vehicle security by a factor of ten. But it’s no longer only your car that could be taken. A cybercriminal gains access to a large amount of data as well as all smart alarm functionalities after hijacking your account and logging into the app in your name. You will be locked out of the system if you simply change your password. After that, the attacker will be able to −

Keep tabs on all vehicle movements.

Activate and deactivate the alarm system.

Lock and unlock your vehicle’s doors.

Cut the engine – even if the car is moving − in some cases.

Enable or disable the immobilizer, an antitheft device that prevents the engine from starting

A cybercriminal can even listen in on discussions inside the vehicle using the antitheft system’s microphone, which is intended for emergency calls, in the case of Pandora alarms. Remember that you can’t fight back because the system is only accessible to the attacker. Doesn’t sound all that appealing, does it?

Is it possible for hackers to hack a smart car?

While the scenario may sound like something out of a science fiction novel, hacking an automobile and taking over its functionality has been shown. An IoT gadget is a smart automobile. Cars are far more complicated than other IoT devices, such as a smart thermostat or any other smart home equipment, yet they share a number of similarities. Smart automobiles, like any other Internet of Things gadget, are connected to networks and exchange data with other devices. As easy as this is, these networks are vulnerable to a slew of security flaws.

The most well-known example of what may go wrong with smart cars was a weakness in the 2014 Jeep Cherokee, which allowed two industry professionals to seize control of the vehicle by accessing its network and then killing it. While security concerns have long been a part of the conversation about smart cars, this incident shocked the industry to its core. Since then, the number of ways to take control of smart automobiles has only grown. Hackers can now attempt to lock car doors remotely and insert malware into various components of the vehicle, allowing the hacker to alter the vehicle’s behavior or prohibit the user from using particular features.

Hackers can also use the system’s flaws to alter how the system responds to the driver’s commands. This isn’t just a hypothetical situation. A 19-year-old security researcher was recently able to remotely open the doors of over 20 Teslas, which is alarming for everyone who owns or wants to buy a smart car.

Those who use their iPhones as automotive remote controls face even greater dangers. There are a number of ways to hack into someone’s phone, and if all of your IoT gadgets are managed through your phone, the threats may easily lead to serious real-life consequences with no immediate resolution in sight.

How to defend your smart car against cyber-attacks?

While it’s undeniable that these concerns must be considered, smart automobiles aren’t going away anytime soon. Rather than swearing off all innovation and convenient smart cars, here are several things you can take to reduce the odds of your car being hacked.

Never forget to update your software

Never forget to check for updates. While the sector is still young, it’s difficult to find a “silver bullet” answer to all concerns. However, one definite approach to reducing the hazards is to keep your connected devices and your car’s software up to date.

Updates are available to improve the device’s overall security, and you don’t want to miss out on any of them. To make the procedure go faster, sign up for manufacturer recalls or software fixes.

Use a virtual private network (VPN)

When using your car’s Wi-Fi to communicate with other devices, use a VPN. It is critical to comprehend the VPN definition in order to properly comprehend its significance. VPNs encrypt your connection, making it nearly impossible for snoopers to link your online activities to you. This will prevent any unwelcome interference or attempts to take control of your network or the vehicle itself. Your connection will be hidden behind a VPN, boosting the security of your network.

Disable any services you aren’t using

Consider your permissions carefully. Don’t stick to the default mode; instead, go over all of the features and reassess what you require. Disable any connectivity ports you don’t use and only enable features you know you’ll use often. There’s no point in enabling all of your car’s features if you’re not going to use them. You can save a lot of avoidable hassle by being cautious and limiting rights.

How To Create And Ring A Sound Alarm In Microsoft Excel

Microsoft Excel includes several built-in tools that allow users to automate conditional formatting (like changing the color of a cell) depending on whether specific conditions are met.

But many people don’t realize it’s possible to make Excel play a sound using Microsoft’s Visual Basic for Applications (VBA). This Excel tutorial will explain how to sound an alarm in Excel when a condition is met.

Table of Contents

How to Ring an Alarm in Excel

Two steps are involved in getting Excel to play a sound based on a particular trigger. First, you must add custom code enabling Excel to play the sound. Then, you need to tell Excel what event or value will trigger the sound.

To do this, you must create a new rule using an Excel VBA macro. This sounds complicated, but don’t worry—all you need to do is copy and paste the code below and then change some basic parameters.

How to Create an Alarm in Excel





to open the pop-up

Microsoft Visual Basic for Applications


Enter the following code:

Function MakeABeep() as String


MakeABeep = “”

End Function

In the

Save as Type

drop-down menu, select





In any cell, type “=MakeABeep()” and press


. If you hear a system sound, your code has worked, and it’s time to move on to the next step.

How to Trigger the Alarm in Excel

Next, you need to add conditional formatting to the cell you would like to play a sound upon a specific event. This will depend on what you want the trigger to be, so you might need to know how to use the various Excel formulas to make it work exactly as planned.

Here’s a basic example showing how to get cell A1 to play a sound if it reaches 100:

Select an empty cell in your Excel worksheet.

When the A1 cell value reaches 101, a system sound will play.

How to Get Excel to Play a Custom Sound

You can get Excel to play multiple custom sounds rather than relying on the single system sound. This way, you can set up multiple alarms to ring when different conditions are met.

Open your





+ F11

to open Microsoft VBA.

In the dialog box, type:

#If Win64 Then

Private Declare PtrSafe Function PlaySound Lib “winmm.dll” _

Alias “PlaySoundA” (ByVal lpszName As String, _

ByVal hModule As LongPtr, ByVal dwFlags As Long) As Boolean


Private Declare Function PlaySound Lib “winmm.dll” _

Alias “PlaySoundA” (ByVal lpszName As String, _

ByVal hModule As Long, ByVal dwFlags As Long) As Boolean

#End If

Const SND_SYNC = &H0

Const SND_ASYNC = &H1

Const SND_FILENAME = &H20000

Function AlarmSound() As String


AlarmSound = “”

End Function



+ S

to save the file.

In the

Save as Type

drop-down list, select





Note: In this template code, “AlarmSound” was used instead of “MakeABeep.” Both of these can be written as whatever you would like. For example, if you wanted multiple alarms to ring for different conditions, you could use “Alarm1,” “Alarm2,” and so on.

What Kind of Alarms Can You Create in Excel?

Here are a few examples of data conditions that you can tell Excel to play an alarm for:

If the value is equal to, greater than, lesser than, or between another value(s)

If the cell is a duplicate

If the cell refers to a particular date (like a due date or expiration date)

If the value is in a specific percentile (for example, the top 10% or above average)

If the cell is a particular color—useful when you have previous conditional formatting rules set up

Data Management Has Never Been Easier

Microsoft Office’s Excel is one of the most powerful data validation and analysis tools on the market and has been for a long time. Whether you want your Excel workbook to display your data in an easy-to-understand manner or format cells to notify you when conditions are met, Excel has the tools for you.

7 Ways to Hack an Android Mobile Phone

While there are numerous ways to hack an Android device, most Android security attacks use one of the following eight methods.

Study these methods of how to hack Android phones carefully so you can learn how to defend yourself.

Method 1: Social Engineering

Android hacking apps are explicitly designed to allow people to hack your Phone, as these Android applications are not available in the Play Store. Instead, hackers can install them from third-party sites.

Developers target these apps toward spouses and partners who want to track what their significant others are doing. They allow you to read your partner’s text messages and browsing history. It also offers geolocation features that let you see exactly where your partner is at any time. You can check if they installed Tinder; some apps even allow you to record their calls.

Method 2: Malvertising Method 3: Smishing

Smishing is a type of phishing attack in which hackers will send you text messages that seem to come from reputable businesses. Companies often use shortcodes to send alerts, including banks, apps like Airbnb, and others.

A hacker may use a shortcode claiming to be your bank. For example, they may send a text message with a link and ask you to review your account security details. The link is usually malicious in one of two ways.

There is an aspect of social engineering to smishing because hackers have to use trustworthy language in their text messages, so they seem to come from your bank. Often, they use fear tactics, such as fake fraud alerts, to make you act quickly without thinking.

Method 4: Malware

Malware is a word that refers to malicious software in general. While smishing is one-way hackers spread malware, there are many other ways malware can get on your Android operating system.

There are many types of malwares as well. Some types of malwares log your passwords and text messages, while others hack your camera. Ransomware is an insidious form of malware that locks your data or device until you pay to have it released. Hackers will demand money in the form of cryptocurrency to avoid tracking. To protect against this, you should install an anti-malware tool.

Method 5: Place Exploit in Android App

One of the reasons Android is a lot more vulnerable to attacks than iPhones is that Google doesn’t do nearly as good of a job regulating its apps as Apple. The Apple Play Store is pretty safe, but malware has found its way into apps that Google approved for the Google Play Store time and time again.

Dozens of apps have had malware in them. People have installed these malware-infected apps alone three million times! Most of these apps often appear innocent enough.

Usually, Google removes these malicious apps from the Play Store once it gets wind of what’s happening. However, that can sometimes take a while.

There are two ways which help you to protect yourself against malicious apps:

The second thing you must do is install an antivirus program to scan the apps you downloaded and check them for viruses.

Method 6: Pretexting

Pretexting is a specific form of social engineering that involves using pretexts to contact you and ask for personal details.

Some examples of pretexts can include:

Pretending you have won the lottery

Pretending you need to secure your account after a failed unauthorized login

Pretending to be your friend who needs you to help them

The latter form is insidious because you often don’t realize anything malicious is happening. Many people are smart enough to realize that it probably is if an offer sounds too good to be true. Many other people also double-check unsolicited text messages to ensure they come from a legitimate source.

However, if someone hacks into your friend’s Instagram account and sends you text messages, you will likely not think twice about trusting them. They’re your friend, after all, and you know them in person.

An attacker might hack into someone’s Snapchat account and send messages with suspicious links to all their friends. Or they may use the pretext of needing help getting a verification code because they lost their Phone. You may think you’re helping your friend log back into their Facebook or bank account, but you’re helping a hacker log into your bank account.

Method 7: Using Multimedia Message (MMS) to Exploit

While you can send malicious links over text, a more dangerous form of hacking involves sending MMS messages. Sophisticated hackers can send malicious videos with lousy code that will execute when you play them. You may not realize what’s happening because this attack is not as evident as a malicious link.

How To Know That Your Phone Is Hacked

The best way to determine if someone hacked your Phone is by running antivirus scans.

Usually, there are other warning signs like:

Lagging Phone

Freezing and crashing

The battery dies much quicker than before

If you notice an unexpected change in battery or overall performance, download antivirus software and run a scan immediately.

How To Prevent Hackers from Getting into Your Phone

Here are the ways to prevent Hackers from Getting into Your Phone:

First, lock your Phone using a password or biometric data. Nobody can install a spy app on your Phone when you’re not looking.

Practice application security (For example, only download apps you trust), and don’t visit pirating websites that may contain malware.

Finally, use antivirus software and run scans regularly. It’s best to use an app with a firewall or continuous monitoring to prevent malware from infecting your Phone.

Why Does Someone Want to Hack Your Android Phone?

There are numerous reasons someone might want to hack your Android Phone.

A suspicious spouse or partner might try to hack your phone to discover your whereabouts and uncover infidelity.

Hackers target your Phone to steal sensitive information. Most people have financial apps, like banking apps, on their phones. Many people store sensitive details on their phones, like their social security numbers or bank account passwords. Some even have pictures of their passports or driving licenses.

Cyber thieves can steal your money and empty your bank accounts by hacking your Phone. They may also be able to access personal information and use that to commit identity theft. For example, they might take out a loan using your Social Security number.

How You can Remove a Hacker from My Phone

If a hacker did manage to get into your Phone, here’s how to remove them.

Get rid of suspicious apps: Find the app tracking you by going to your app list in your phone settings. Make sure to include system apps. Remember, these apps don’t usually show up on your home screen, as they hide their app icons from your screen.

Install an antivirus application: Install an antivirus application that can scan for malware and remove it.

Find the reason behind your phone hacking: Finally, figure out how the hacker hacked your Phone in the first place and be smarter next time.

How To Choose The Right Smart Home Light Bulbs

Gone are the days when The Clapper was the most convenient way to turn on the lights inside your home. The world of smart home products has made The Clapper look like a relic of a long-forgotten past. Even the light switch is looking at its own potential demise as smart bulbs grab the future by the horns. Switching lights on remotely with a smartphone is the present trends. With that comes the need to choose which smart light bulbs to put in your home. So how do you make that decision? Let’s look at the right way to choose the best smart home light bulbs.

Why Smart Home Lighting?

Smart home lighting is a matter of convenience. To be clear, let’s not confuse convenience with laziness. We are not necessarily talking about sitting on the couch and turning on the lights with your app because you do not want to get up. One of the better uses is for security. Smart light bulbs are a great way to make people think you are home even when you are not. Setting your lights to run on a schedule can make it look like your home is occupied and deter potential thieves. This is one of the most under-appreciated reasons to have smart home lighting.

Another reason is the ability to make your children think you have magical powers. The look on a child’s face when you turn on the lights with a voice command is magical. In all seriousness, that’s not the only reason to buy smart bulbs, but it’s a pretty good one.

Picking a Platform

When it comes to actually choosing the right smart home bulbs, the most important decision is the platform. While it seems ironic, choosing a platform is critical to making sure you have the right setup now and down the line. That means you need to decide first and foremost if you are on team Google Home, team Apple HomeKit or if you want to roll with Amazon Alexa. Each of these three services is popular and they are all capable of being the central point of control. But wait, what about Zigbee or Z-Wave? These hub options can also serve as your platform of choice and should not be forgotten as options. As you can tell, you have choices and it all starts with selecting the platform that works best for you. 

What Do You Want to Control?

While the initial reaction to this question is undoubtedly that you want to control your lights, there is more to consider. There are various types of lighting in your room that you have to decide about controlling. Do you want to keep things simple and just control your kitchen or bedroom lights? Do you want to only control indoor lighting or do you want to add outdoor lighting to the mix? What about lamps around the house? Do you want to control those as well? These questions are just a sample of what you need to ask yourself to help determine which smart home bulbs are right for you.

Time to Choose

The most popular smart home lighting option is unquestionably, the light bulb. These bulbs screw into your existing lighting systems, whether they are recessed or attached to a lamp. The good news is that there is a wide selection of available options to choose from. The bad news is there is also a large selection to choose from which can be paralyzing for first-time buyers. There are plenty of strong names out there to evaluate including Wyze, Sengled, Philips Hue, Osram and Sylvania. By and large, a smart home bulb should cost roughly around $15 per bulb. That’s a fairly standard price when these are not on sale.

Fortunately, there are starter kits like the Philips Hue Starter Kit to help you get things going. This system includes 3 LED smart bulbs that can fit lamps, overhead lights and 4-inch recessed cans. It also includes the Hue hub that can control up to 50 total bulbs without affecting your home Wi-Fi speeds. Finally, it also comes with a smart button mounting plate that enables control over the lights without a smartphone. This particular unit only includes white dimmable bulbs so you have to look at another option if you want to get colorful.

If you want to get some color going with your smart light bulbs, Philips has a color ambiance starter kit with four bulbs and a hub. Again, it all comes down to your particular needs and taste. Do you want to keep things simple and inexpensive? Go for the white starter kit. Do you want to go with something that has a little more flare? Then go for the color ambiance kit. You cannot go wrong either way. 

Choosing the right smart home bulb is not rocket science, but it does require some considerations. The last thing you want to do is dive headfirst into this pond without thinking about what you really want to accomplish. Once you have the answer to that question, you’ll know exactly what to buy.

The Lunar Rover: Designing And Unpacking A Car On The Moon

It wasn’t until after Apollo 11 landed on the Moon that NASA starting thinking seriously about giving astronauts some sort of surface mobility system, a vehicle that would allow them to cover more ground during their brief sojourns on the lunar surface. In early 1970, the space agency award Boeing a contract to develop and build such a system. And Boeing delivered. The company delivered the first flight ready lunar rover to NASA on March 15, 1971, just 17 months after winning the contract and two weeks ahead of schedule. This rover flew on Apollo 15, and while taking a car to the Moon might seem insane, the rover’s simple and elegant design made it a worthwhile addition to the final three Apollo missions.

Apollo 17’s lunar rover on the Moon

Increasing Surface Mobility

Forward-thinking engineers had been dreaming up ways to increase astronauts mobility on the lunar surface since the early 1960s. Some wanted to see full roving laboratories akin to mobile homes — designs like MOLAB — serve double duty as crew quarters and traveling workspace on lunar missions. Others favoured worm- and centipede-inspired vehicles that would distribute their weight across a larger surface area to avoid sinking into the dust. Still other proposals imagined flying platforms that would give astronauts a bird’s eye view of the lunar terrain as they traveled from place to place. There was even, briefly, serious interest in sending astronauts to the Moon with electric mini-bikes.

The reality was that a car-like vehicle was ideal. Stable on four wheels and flat, it could carry two astronauts and their life support systems and tools to interesting sites a fair distance from their landing site.

But the design constraints for the lunar rover were strict. As was the case with the Apollo program on the whole, weight was something NASA didn’t have a lot of wiggle room with. The rover would have to be light enough to launch with the Apollo payload as it was, but also be sturdy enough to traverse all types of terrains, conquer slopes up to 25 degrees, and function in temperatures ranging from -279 to 243 degrees Fahrenheit. And like everything designed for use on the Moon, it had to be something astronauts could unload and use easily wearing their bulky pressure suits.

The final rover that Boeing built met these strict specifications. It was an electrically propelled vehicle that weighed 480 pounds on Earth (80 pounds on the Moon), could carry about twice its own weight, and move at a top speed of about 8.6 miles per hour. Physically, it was an open design with two seats and a central control panel with a joystick that either astronaut could manipulate with a bulky glove on.

But designing it was only half the battle. The rover would be useless if engineers couldn’t figure a way to get it down to and ready to drive on the lunar surface.

The steps to deploy your lunar rover.

**Getting the Rover to the Moon **

Luckily, the Apollo lunar module had enough storage space on board to carry a folded lunar rover. With its wheels folded in and its forward and rear chassis (or frame) folded over its middle section, the rover fit snugly into the LM descent stage’s quadrant 1, one of four storage units on the lower portion of the spacecraft.

The folded rover was anchored to the LM at one upper central strut on the lander’s body and to two points on its lower portion. Keeping it in this stowed position was a system of cables, shock absorbers, pin retract mechanisms, telescoping tubes, push—off rods, and a handful of other minor gears all designed so one astronaut could unpack the vehicle alone.

Deployment started with a single mylar cable attached to the rover’s aft chassis. One astronaut pulled this tape end over end to start the sequence then handed it off to his moonwalking companion to keep tension on the cord. Next, the first astronaut climbed up the lunar module’s ladder to pull a D-ring that released the rover’s upper restraint. This let the rover to fall about five inches away from its stowed position. It couldn’t go any further; two cables kept it in place.

Stuck in this half-released position, the first astronaut then walked around to the rover’s other side to pull a second mylar cable. This tape lowered the rover slowly to the surface. It also released two support cables that in turn triggered a push-off tube that moved the rover’s centre of gravity outward away from the lunar module. As it descended, release pins on the chassis pulled out to allow the base of the vehicle to unfold. Then the wheels sprung into place automatically thanks to torsion bars.

The astronaut continued pulling this mylar tape until all four wheels touched the surface and the support cables went slack. Another mylar tape on the other side of the rover brought the vehicle the rest of the way to the surface while telescoping tubes made sure it came to rest safely away from the lunar module. The cables and tubes released once their job was done. The rover was on the surface.

How the Apollo lunar rovers stack up against other offworld rovers.

Success on the Surface

With the rover unpacked, the astronauts had to set up the vehicle before they could take it for a drive. They deployed fender extensions over each wheel, inserted toeholds, deployed handholds and footrests, set up the control and display console, unfolded the seats and released the seatbelts, and finally discarded all the now unnecessary locking pins and latches.

The lunar rover turned out to be well worth the rapid development schedule. On the first three lunar landing missions — Apollo 11, Apollo 12, and Apollo 14 — astronauts covered a total combined distance of 4.4 miles. With a rover, Apollo 15 more than tripled that distance covering a total of 17 miles. Apollo 16 covered slightly less ground, just 16.8 miles. The final lunar Apollo mission, Apollo 17, that got the most out of its rover. In December of 1972, Gene Cernan and Jack Schmitt traveled 4.5 miles from their landing site, which was further than any other crew had gone, covered a total distance on the surface of 22.2 miles, and reached a top speed of about 11.5 miles per hour.

The variety of sites Apollo astronatus were able to visit with the luanr rover gave us far more scientific return from these missions than we would have been able to gather otherwise, deepening our understanding of the lunar environment and the Moon’s evolution. These missions also gave us incredible footage that continues to make Earth-bound drivers extremely jealous.

How To Manually Create A System Restore Point In Windows 10

You’ve probably read several troubleshooting articles that warn you to create a System Restore Point before making potentially drastic changes to your Windows computer. If you have no idea what a System Restore Point means, think of it as a backup copy of your PC’s settings and other vital system files.

Say you installed a malicious program or deleted a registry file by accident, and your computer begins to malfunction, you can easily undo these (unwanted) changes by performing a System Restore. That allows you to revert your computer to an initial state (called Restore Point) when things were working smoothly.

Table of Contents

In this guide, we’ll explain how System Restore works in Windows 10 and teach you several ways to manually create a system restore point. 

Enable System Protection on Windows

System Protection is a section of the Windows OS where restore points are created and managed. To create restore points, you need to first have System Protection enabled on your device. Although some computers have this feature activated by default out-of-the-box, others may require you to manually turn it on.

Windows automatically assigns about 3 – 10 percent of your hard drive for System Protection. You can change this by adjusting the Max Usage slider. However, make sure you assign at least 1GB (or more) because the System Protection feature won’t run if the reserved disk space is below 1GB.

If the reserved space gets occupied, Windows will delete older restore points to make room for new ones. We recommend that you proceed with the default disk space that Windows recommends.

The default allocation should be enough to accommodate as many restore points as possible. The more restore points you have, the higher the chances of recovering files, settings, and other configurations should your computer ever run into a problem.

With System Protection set up, you can now manually create restore points.

Manually Create a System Restore Point

Windows automatically creates restore points when you enable System Protection. It does so once every week or prior to significant events like a Windows update, driver installation, etc. You can also manually create a restore point if you’re making system-altering changes to your computer. For example, it’s always recommended to manually create a restore point before making changes to the Windows Registry.

Windows will create the restore point and display a success message when done.

The creation process may take a couple of minutes, depending on the sizes of files in the restore point as well as your drive’s performance.

Create a Restore Point Using Windows PowerShell

There are usually many ways to get things done on Windows. You can swiftly create a restore point in seconds using the Windows PowerShell. All you need to do is paste some commands in the PowerShell console; we’ll show you how.

Paste the command below in the PowerShell console and press Enter.

powershell.exe -ExecutionPolicy Bypass -NoExit -Command “Checkpoint-Computer -Description ‘Restore Point Name’ -RestorePointType ‘MODIFY_SETTINGS’”

Note: You can replace the “Restore Point Name” placeholder in the command with any description of your choice.

Windows will create the restore point when the progress bar hits 100%.

How to Recover Changes Using System Restore

Now that you’ve created a restore point, how do you use it to revert to an earlier point if your PC runs into issues? Perhaps, you recently installed a Windows update or network driver that messed up your internet connectivity. Here’s how to undo system changes using System Restore.

Can’t find a restore point in the System Restore window? Refer to this troubleshooting guide on fixing missing restore points on Windows.

Windows Won’t Boot? Here’s How to Perform a System Restore

The technique above shows you how to undo changes with System Restore when your computer is on. But what if your computer won’t start up at all? Or perhaps Windows boots correctly but crashes before you get to the System Restore window? How then do you restore your device?

Like we mentioned earlier, Windows often provides multiple ways to get things done. So, if your PC won’t properly load Windows, you can initiate a system restore from the Advanced Startup Options menu.

Power off your PC and turn it back on. Press and hold the power button as soon as the Windows logo appears on the screen to shut down your PC again. Repeat this three times and your PC should boot into the Windows Recovery Environment. 

Never Lose Important Files & Settings

You’ve learned how to manually create a system restore point and how to perform a system restore, even when your computer won’t boot. However, you should note that a system restore isn’t a backup solution; it only saves system files and settings, not your personal data. 

In addition to manually creating a restore point, we also recommend creating a System Image Backup or a recovery CD/USB drive. With these, you can restore your computer (including all installed programs, settings, files, etc.) to a previous state should your PC get corrupted to the point where it won’t load Windows.
